Estimation of Livestock Manure Nitrogen Load and Pollution Risk Evaluation of Farmland in Daxing District
大兴区农用地畜禽粪便氮负荷估算及污染风险评价

Based on the livestock statistical data,the nutrient content of livestock manure was calculated and the nutrient transformation from livestock manure to farmland was realized by using the method of spatializing livestock manure nutrient.On this basis,this paper calculated nitrogen load of livestock manure combining with the area of farmland and realized the estimation of nitrogen load of livestock manure and potential pollution evaluation in landmass for unit taking Daxing District in Beijing as an example....
